Also the mechanism whichsupports the barrels should be adapted'to discharge the same after thecoating process is completed, and the discharging means should also beadapted to handle the barrel without contacting with the freshly coatedsurface. It is among the objects of my, invention to-provide a mechanismwhich shall revolubly support a barrel or cylindrical article in theabove described manner.

The mechanism to be used in connection with the coating of barrels orcylindrical articles should be adaptable to be used with articles ofvarying lengths and diameters, and should be capable of adapting itselfto handle such varying sizes with a minimum amount of adjustment whichinterferes with the operation of the machine. It is a further o ject ofmy invention to provide a mechanism which shall be adaptable to handlebarrels len hs and diameterswithout the necessity o 'more than a minimumof adjustment of the various operative parts. Other objects of myinvention willappear as the description roceeds.

To the accomphshment of the foregoing and related ends, said invention,then, con-' sists of the means hereinafter fully described andparticularly pointed out in the claims; the annexed drawings and thefollowing description setting forth indetail certain mechanism embodyingthe invention, such disclosed means constitutin however, but'one ofvarious mechanical orms in which the principles of the invention may beused.

Referring more specificallyto the drawings, and more especially to thosefigures in which like ordinals are employed to designate like parts. Theordinals 1 and 2 are employed to designatethe longitudinal sides. of thebase frame on which the mechanism is mounted and 3and 4 desi bers ofsuch frame. Positioned on the side frame members 1 and 2 aretransversely ex'- tending frames generally indicated by 5 and 6. Theframes 5 and 6 are adapted to be moved longitudinally of the side frames1 w and 2 by means of racks 7 and 8 being engaged by pinions 9 and 10,-which are rigidly secured to transverse shafts 11 and 12. The

shafts 11 and 12 have bevel gears 13 and 14 'securedthereto which are inmesh with similarly formed gears 15 and 16 terminally mounted on shaft17. Actuation of this frame-moving mechanism is accomplished by asuitable crankhandle (not shown) engaging the extension 18 of the shaft12. Upon 5 rotation of the shaft 12 by such handle or crank thetransverse frames 5 and 6, with their associated mechanism, can be movedaway from or toward each other, as most clearly shown in the dotted andfull line po= sitions illustrated in Fig. 2. The transverse. frame 5 hasrevolubly mounted thereon shafts 20 and 21 which are journaled inbearings 22 and 23 which are removably secured to the transverse frame'5 by means of bolts 24 and 25. Terminally mounted on the shafts 20 and'21 are rollers 26 which have'their main portions preferably conical inform as at 27 and which1, have-circumferential flanges 28 formed'on oneend. thereof. The shafts 20 and 21 have collars 29 mounted thereon whichserve'as axial re straming means for these shafts in their bearings.Shafts 20 and 21 also carry sprocket wheels 30 which are interconnectedby a flexible chain 31.

Mounted onthe terminal portion of the base of the machine, as mostclearly shown on the leftin Fig. 2, is a transversely extend- 1 mgplatform 32, which hass'ecurely mounted 00 gnate the end mem-.

' thereon a prime mover 33, here shown in the i shown).. The shaft 37 asadriving form of an electric motor. The drive shaft 34 of the motor33has a driving gear 35 rigidly secured thereto which meshes with adriven gear 36 mounted "on a shaft 37. The shaft 37 extendslongitudinally of the machine and is suitably journaled in s acedbearings, (not I pm1 on 38 rigidly secured thereto which mes es w1th adriven gear 39 secured to the shaft 20.

- The construction of the transverse frame 6 and its associatedmechanism is identical with that just described in connection withtransverse frame 5 so that like ordinals bearing prime marks will beemployed to desilg; nate similar parts on the two frames.

' connectionwith the mechanism as shown mounted on the transverseframes5 and 6 and the gearing in communication with the motor it w1ll be notedthat all such mechanism an gearing is suitably enclosed in guards, suchas 40, which protect such mechanism from the paint and like materialwhich would be injhlirious to the operation thereof. v

ounted in bearings 41 and42, which are respectively carried b 5 and 6,is a 'longitu he transverse frames ally extending shaft 43, whichhas acollar 44 shown associated therewith to prevent axial movement thereofwith respect to the bearing 41. The shaft 43 has rigidly mounted thereona member 45 which is axially restrained with respect to the shaft 43. bmeans of a collar 46. As most clearly s own in Figs. 2 and-3 the member45 has an extending army which is terminally formed intoa pad 48 adaptedto receive the foot of the operator. The-p110 jecting' element 49' ofthe member 45 has rigidly secured thereto an operating handle 50 bymeans of bolts 51.

Rigidly secured to the shaft 43 is a radi- -ally extending arm 52 whichis terminally adapted. to receive a stub shaft 53 which is securedthereto b means of a nut 54 enga ing the threade end thereof. Revolub ysup orted by the stub shaft 53 is a roller pre erably conical-in formand somewhat similar to roller 27, and which is axially restrained withrespect to the shaft 53 by means ofthe nut 56. The shaft 43 has anotherradially extendin arm 57 revolubly secured thereto, but axia 1y slidablethereon, which arm 57 has a roller similar to roller revolubly securedthereto in the same manner.. As most clearly shown in Fig. 1, bracketmember 58 is secured to the transverse frame 6 by means of a. bolt 59,and extending laterally therefrom has an upwardly bent end 60 and asimilarly directedprojection 61 which rojections are adapted to enga eoppositeaces of the hub 62 of the arm 5 In this manner the arm 57 ismaintained in the proper relation to the rollers 26 as'the transverseframe 6 is moved along the bed of the .machine.

, at the terminals thereof so that when The sides of the transverseframes 5 and '6 opposite the shaft 63, which is journaled in thebearings 64 and 65. The shaft 63 has a collar 66 rigidly securedthereto, which serves as an axial restraining means for this shaft withrespect to the frame 5. Terminall mounted on the shaft63 is a member 66whlch has an arm 67 formed integrally therewith and extendin radiallytherefrom. The terminal portion 0 the arm67 is adapted to receive a pin68 by means of which. a lever 69 is oscillatably secured thereto. Theoppositeend of the arm 69 is secured .to the lever 50 by means of a pin70.

Rigidly secured to the shaft 63 at a point adjacent the transverse frame5 is a rocker .63 has slidably keyed thereto at a point adjacent theframe member 6 another rocker member 71" which is formed similarly tothe rocker member just described. The rocker member 71' has associatedtherewith a bracket similar to the bracket 58, which likewisemaintainsthe rocker member 71"in proper relation with respect to. thetransverse frame 6.

In the barrels to from a preferably inclined runway extending to theright of the machine, as viewed in Fig. 3. The barrels rest against theends 74 of therocker members until the shaft 43 is rotated in acounter-clockwise direction, due to actuation b the operator of eitherthe .pedal 47 or t e control handle 50. This counter-clockwise rotationof the shaft 43, through the arm 69, causes the clockwise rotation ofthe-shaft 63, which moves the rockter members 71 and 71' into theosition shown in dotted lines in Fig. 3. en the rekers 71 and 71' are inthisposition, a barreP -is permitted to roll thereon which, upon areverse movement of the rockers, is permitted to roll onto thesupporting rolls 26 and 26'. After the barrels ave been coated anactuation of the shafts 43 and 63 in themanner just described will causea counter-clockogaration ofthis mechanism, the

wise rotation of the arms 52 and. 57, which i will cause the rollers "55to engage the barrels at the peripheries thereof and laterally move thesame oi the rollers 26 and 26' onto receiving skids (not shown).

By a proper actuation of the shaft 18, which will impart rotation -tothe shaft 17, the transverse frames 5'and 6 may be so s 'aced that thedistance between the circumf tial flan es 28 and 28 on the rollers 26and 26' will just the length of the barrel which is to be received bythe machine. When the transverse arms 5 and 6 are so ositioned on thebase the barrels or like cylmdrical articles will be supported on theirperi heiries coated are fedto the machine 9 erenrels are rotated and thecoating applied thereto the fresh coating will not be marred by thesupporting mechanism. The rollers 55, which are associated with thedischarge arms 52 and 57 are adapted to similarly engage the barrel orcylindrical article so that when the barrel has once been coated theexterior thereof will in no way be marred incidental to its movementfrom the painting machine.

The motor 33, through the gear train described in connection therewith,effects a positive drive to each roller of the machine so that aconstant rotation of the supported barrel takes place while the barrelis positioned on the machine, which rotation permits the operator tospray or otherwise apply the coating to the barrel over its entireperiphery.

It will be seen in connection with the above description that themechanism comprising my invention is particularly applicable to be usedin the coating of barrels and like articles and that the manner in whichsuch barrels are subjected is different from, and has advantages over,any means heretofore em ployed to support cylindrical articles duringthe coating process. Only so much of my invention has been described ashas been considered pertinent to the operation thereof and thedescription is believed to be sufiicient for those acquainted with theart of coating cylindrical articles, suffice it to say that detailchanges might be made in the various forms of the construction herechosen for purposes of illustration without in any way departing fromthe principles of my invention.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as myinvention 1. In a mechanism of the character describe the combination ofspaced paired rollers having their peripheries oppositely inclined toradially and axially support a cylin drical article by engaging itsperiphery at the terminals thereof, and rollers revolubly mounted onarcuately movable arms adapted to similarly engage such article and movethe same off said first named rollers.
